Description

Die Erfindung betrifft ein textiles Flächengebilde für Bettsysteme, wie Schutzbezüge, Kissen, Oberbetten oder Matratzen.The invention relates to a textile fabric for bedding systems, such as protective covers, pillows, duvets or mattresses.

Zweck der Erfindung ist, mit Milben- und allergendichten Schutsbezügen, die in Kissen, Oberbetten oder Matratzen lebenden Milben abzusperren und dadurch zu verhindern, dass die Milben und/oder Milbenallergene nach außen gelangen. Dabei soll das Milben- und Allergenrückhaltevermögen garantiert sein, kein Luftaustausch (Luftdichtigkeit), dagegen ein ausreichender Feuchtigkeitsaustausch stattfinden und der Liege- und Schlafkomfort nicht beeinträchtigt sein. Zudem sollen die Schutzbezüge wasserdicht, frei von Schadstoffen und waschbar sein. Außerdem sollen keine Sekrete und damit Viren oder Bakterien in die Kissen oder Decken gelangen können.The purpose of the invention is to mitigate mites living in cushions, duvets or mattresses and to prevent the mites and / or mite allergens from escaping to the outside with mite and allergy-proof covers. The mite and allergen retention should be guaranteed, no exchange of air (airtightness), on the other hand, a sufficient exchange of moisture take place and the lying and sleeping comfort should not be impaired. In addition, the protective covers should be waterproof, free of pollutants and washable. In addition, no secretions and thus viruses or bacteria can get into the pillows or blankets.

Eine weitere Forderung in diesem Zusammenhang ist, statische Elektrizität, die durch reibende Bewegungen im Bett durch eine im Bett liegende Person erzeugt werden kann (Body Voltage), zu neutralisieren, weil diese elektrische Aufladung Milbenallergene aus, dem Innern eines Kissens, eines Oberbetts oder einer Matratze anziehen kann.Another requirement in this context is to neutralize static electricity that can be generated by rubbing movements in bed by a person lying in bed (body voltage), because this electrical charge mite allergens from, the inside of a pillow, a top bed or a Can put on mattress.

Aus dem deutschen Gebrauchsmuster DE 201 01 149 U1 ist ein gewebter oder gestrickter Matratzenbezugsstoff bekannt, in dem auf bestimmten Abständen von nicht mehr als 2 cm voneinander angeordnete, elektrisch leitende Garne eingearbeitet, z. B. eingestreckt oder eingewebt sind, die z. B. einen elektrisch leitenden Kern aufweisen, der von einer elektrisch isolierenden Außenschicht umgeben ist. Die Verwendung elektrisch leitender Garne soll durch elektrische Felder verursachten Schlafstörungen durch Vermeidung elektrischer Aufladungen entgegenwirken, denn elektrostatische Aufladung kann zu schlechtem Schlaf führen. Die Wirksamkeit dieser textilen Stoffe ist jedoch nicht befriedigend, weil die elektrische Ableitung nicht optimal ist.From the German utility model DE 201 01 149 U1 is a woven or knitted mattress fabric known in which incorporated at intervals of not more than 2 cm from each other, electrically conductive yarns, z. B. are stretched or woven, the z. B. have an electrically conductive core, which is surrounded by an electrically insulating outer layer. The use of electrically conductive yarns is intended to counteract sleep disturbances caused by electric fields by avoiding electrical charges, since electrostatic charging can lead to poor sleep. The effectiveness of these textile fabrics is but not satisfactory, because the electrical discharge is not optimal.

Zudem soll eine derartige Textilie durch Neutralisation elektrischer Aufladungen bewirken, dass keine Milbenallergene oder dergleichen Partikel anziehende, elektrostatische Kräfte entstehen..In addition, such a textile should cause by neutralization of electrical charges that no mite allergens or similar particles attracting, electrostatic forces arise.

Diese bekannten textilen Stoffe sind nicht luftdicht und wasserdicht und weisen meist schlechte physiologische Eigenschaften bezüglich Feuchtigkeitstransport und Thermoregulation auf und sind deshalb insofern, nur bedingt verwendbar. Außerdem ist die Neutralisierung der elektrischen Aufladung auch nicht ausreichend, um zu verhindern, dass die Allergene - angezogen durch elektrostatische Kräfte - aus einer Matratze, einem Kissen oder einem Oberbett nach außen dringen.These known textile fabrics are not airtight and waterproof and usually have poor physiological properties with respect to moisture transport and thermoregulation and are therefore insofar, only conditionally usable. In addition, the neutralization of the electrical charge is also not sufficient to prevent the allergens - attracted by electrostatic forces - from a mattress, a pillow or a blanket to the outside penetrate.

Des Weiteren ist eine Abschirmdecke gegen elektromagnetische und sonstige Strahlungen bekannt, die den Benutzer auch gegen allergene Bestandteile szhützen soll ( DE 201 02 560 U1 ). Diese Abschirmdecke gegen elektromagnetische und sonstige Strahlungen, insbesondere für Sitz- und Liegebereiche, weist eine elektrisch leitendes Material enthaltende Abschirmlage mit einer Decklage aus nicht leitendem textilen Material kombiniert auf, wobei die Abschirmlage in zumindest einer Textillage vorwiegend aus feinem und dicht verteiltem metallisiertem oder elektrisch leitendem Fasermaterial besteht, die zwischen zumindest zwei Decklagen aus einem staubdichten Tuch eingeschlossen ist. Der Schutz gegen allergene Bestandteile soll durch die Dichtigkeit des Tuchs gewährleistet werden.Furthermore, a screening blanket against electromagnetic and other radiation is known, which is intended to protect the user against allergenic components ( DE 201 02 560 U1 ). This shielding against electromagnetic and other radiation, especially for sitting and lying areas, has a shielding layer containing electrically conductive material combined with a cover layer of non-conductive textile material, wherein the shielding in at least one textile layer mainly of fine and densely distributed metallized or electrically conductive Fiber material is included between at least two cover layers of a dust-tight cloth. The protection against allergenic components should be ensured by the tightness of the cloth.

Des Weiteren sind aus der DE 40 27 798 A1 Materialien bekannt, bestehend aus einem geschlossenen, also nicht porösen Film aus wasserdampfdurchlässigem Polyurethan, der durch eine textile Komponente verstärkt ist, die sich zur Herstellung von Matratzenhüllen eignen sollen. Die Materialien sollen vorhandenen Milbenkot zurückhalten und zum Absterben der Milben führen, weil den Milben die Nahrung (Hautschuppen) entzogen wird.

Als flächige Textilie wird z. B. ein Gewebe, Gewirke, z. B. Gewirke mit Schusseintrag, Gestrick, Vliesstoff oder dergleichen mit Flächengewichten von 10 bis 500, insbesondere von 30 bis 100 g/m2 verwendet. Die Textilie besteht vorzugsweise aus Polyamidfilamertgarnen, Polyesterfilamentgarnen oder Baumwolle bzw. Polyesterfasern oder Polyamidfasern oder Mischungen daraus beim Vliesstoff. Die Feinheiten der Garne liegen zweckmäßigerweise zwischen 11 und 1100 dtex.

As knitted fabric with weft insertion, knitted fabric, nonwoven fabric or the like with basis weights of 10 to 500, in particular from 30 to 100 g / m 2 is used. The textile preferably consists of polyamide filament yarns, polyester filament yarns or cotton or polyester fibers or polyamide fibers or mixtures thereof at the nonwoven fabric. The finenesses of the yarns are suitably between 11 and 1100 dtex. However, it is also possible to use Kevlar, aramid, glass or the like high-performance fibers or filaments and mixtures of these products.

Vorzugsweise wird ein Gewebe oder Kettengewirke mit Schusseintrag oder Vlies als flächige Textilie verwendet.Preferably, a woven or warp knitted fabric with weft insertion or fleece is used as a flat textile.

Als elektrisch leitfähige sich kreuzende Garne werden insbesondere Filamentgarne mit Feinheiten zwischen 11 und 1100 dtex verwendet, die vorzugsweise in die flächige Textilie eingebracht, z. B. eingewebt sind. Vorzugsweise wird ein an sich bekanntes, sogenanntes Kern-Mantel-Garn verwendet mit Feinheiten zwischen 30 und 200 dtex aus Filamenten mit einem Kernfilament aus z. B. einem Monofil-Carbon-Filament und einer Ummantelung aus z. B. Polyester oder Polyamid. Dabei ist das elektrisch leitende, insbesondere als Kernfilament ausgebildete Kernmaterial innerhalb der Ummantelung dieser zweikomponentigen Garnfilamente eingebettet und erstreckt sich radial nicht bis an die Ummantelungsoberfläche. Zweckmäßigerweise ist das Kernfilament mindestens bilobal, insbesondere trilobal oder aber auch mehrlobal bzw. zwei-, drei-, vier-, fünf- oder sechslappig, wie in der DE 690 13 395 T2 offenbart, ausgebildet. Derartige Garne erfordern keine Erdung zur Ableitung einer elektrostatischen Aufladung. Sie entladen durch Luft-Ionisation durch den sogenannten Corona-Effekt bzw. CoronaEntladung. Für die jeweils parallel verlaufenden elektrisch leitenden Garne der sich kreuzenden Garne wird zweckmäßigerweise ein Abstand voneinander zwischen 4 und 100, insbesondere zwischen 6 und 35 mm gewählt.In particular filament yarns with finenesses between 11 and 1100 dtex are used as electrically conductive intersecting yarns, which are preferably introduced into the planar textile, for.

In this case, the electrically conductive, in particular formed as a core filament core material is embedded within the sheath of these two-component Garnfilamente and does not extend radially to the shell surface. Conveniently, the core filament is at least bilobal, in particular trilobal or even mehrlobal or two, three, four, five or six lobes, as in DE 690 13 395 T2 disclosed trained. Such yarns do not require grounding to dissipate electrostatic charge. They discharge by air ionization through the so-called corona effect or corona discharge. For the parallel running electrically conductive yarns of the crossing yarns is expediently a distance from each other between 4 and 100, in particular selected between 6 and 35 mm.

Die Klebstoffpunkte bestehen aus Schmelzklebstoffen und weisen einen Durchmesser z. B. zwischen 0,15 und 10 mm und eine Verteilung von 3 bis 100, insbesondere von 6 bis 18 g/m2 auf.The glue dots consist of hot melt adhesives and have a diameter z. B. between 0.15 and 10 mm and a distribution of 3 to 100, in particular from 6 to 18 g / m 2 .

Die Membranfolie besteht vorzugsweise aus PTFE, PET oder PU oder Polyethersulfon- oder Polyacrylnitrid oder Celluloseacetat und weist z. B. einen Wasserdampfdurchgangswiderstand, (gemessen nach ASTM E96-2000 Variante E), von 500 bis 6000 g/m2 x 24h sowie Flächengewichte zwischen 5 und 200 g/m2 auf und leitet die Wasserdampfteilchen insbesondere molekular durch die Folie.The membrane film is preferably made of PTFE, PET or PU or polyethersulfone or polyacrylonitrile or cellulose acetate and has z. B. a water vapor transmission resistance, (measured according to ASTM E96-2000 variant E), from 500 to 6000 g / m 2 x 24h and basis weights between 5 and 200 g / m 2 and directs the water vapor particles in particular molecularly through the film.

Das erfindungsgemäße textile Flächengebilde weist insbesondere einen elektrischen Abschirmfaktor S nach DIN EN 1149-3 zwischen 0,39 und 0,75 auf. Der nach DIN EN 1149-1 2006 gemessene Oberflächenwiderstand liegt vorzugsweise zwischen 5 x 1010 und 1 x 1012 Ohm. Des Weiteren liegt der nach DIN EN 1149-5 bestimmte Halbwertzeitfaktor mit t50 < 1 s überraschend niedrig.The textile fabric according to the invention has in particular an electrical shielding factor S according to DIN EN 1149-3 between 0.39 and 0.75. The surface resistance measured according to DIN EN 1149-1 2006 is preferably between 5 × 10 10 and 1 × 10 12 ohms. Furthermore, the half-life factor determined according to DIN EN 1149-5 with t 50 <1 s is surprisingly low.

Das erfindungsgemäße textile Flächengebilde schirmt somit nicht nur gegen elektromagnetische Strahlung ab, sondern leitet auch besonders effektiv elektrostatische Ladungen ab, so dass aus elektromagnetischen Feldern resultierende Schlafstörungen bei empfindlichen Personen und auf Allergene wirkende elektrostatische Anziehungskräfte vermieden werden können. Synergistisch wird durch die Membranfolie der Weg für Milben und Milbenallergene versperrt und gute physiologische Eigenschaften bezüglich Feuchtigkeitstransport und Thermoregulation beim Einsatz in Schlafsystemen gewährleistet. Da das erfindungsgemäße textile Flächengebilde geschmeidig bzw. flexibel ist, wird auch der Liege- und Schlafkomfort nicht beeinträchtigt.The textile fabric according to the invention thus not only shields against electromagnetic radiation but also conducts electrostatic charges particularly effectively so that electrostatic forces of attraction resulting from electromagnetic fields can be avoided in susceptible persons and allergens. Synergistically, the membrane film blocks the path for mites and mite allergens and ensures good physiological properties with regard to moisture transport and thermoregulation when used in sleep systems. Since the textile fabric of the invention is supple or flexible, the lying and sleeping comfort is not affected.

Das erfindungsgemäße textile Flächengebilde ist häufig waschbar, insbesondere auch in industriellen Waschanlagen, ohne dass der Verbund zwischen der Membranfolie und der flächigen Textilie oder die beschriebenen besonderen Eigenschaften verloren gehen.The textile fabric according to the invention is frequently washable, in particular also in industrial washing installations, without losing the bond between the membrane film and the flat textile or the special properties described.

Anhand der folgenden Ausführungsbeispiele wird die Erfindung verdeutlicht.Reference to the following embodiments, the invention is illustrated.

  • Kern-Mantel-Garn im Schuss:
    • Feinheit 39 dtex f 6 x 1; mit Filamenten mit einem Kern aus trilobalem Monofil-Carbon-Filament und einem Mantel aus Polyester;
  • Gewebebindung: X Köper 2/2;
  • Kettfadendichte: 230 Kettfäden/dm, wobei für jeden 44.
  • Kettfaden das Kern-Mantel-Garn eingesetzt ist; dies ergibt einen Abstand zwischen zwei benachbarten Kern-Mantel-Garnen in Kettrichtung von 16 mm;
  • Schussfadendichte: 155 Schussfäden/dm, wobei für jeden 24. Schussfaden das Kern-Mantel-Garn eingesetzt ist; dies ergibt einen Abstand zwischen zwei benachbarten Kern-Mantel-Garnen in Schussrichtung von 16 mm;
A fabric of the following construction is produced as a flat textile:
  • Warp: filament yarn, 100% polyester textured, fineness 78 dtex f 24 x 1;
  • Weft: Filament yarn of 100% polyester textured, fineness 50 dtex f 36 x 2;
  • Core coat yarn in the chain:
    • Fineness 39 dtex f 6 x 1; filaments having a core of trilobal monofilament carbon filament and a polyester sheath;
  • Core coat yarn in the weft:
    • Fineness 39 dtex f 6 x 1; filaments having a core of trilobal monofilament carbon filament and a polyester sheath;
  • Tissue binding: X twill 2/2;
  • Warp density: 230 warp threads / dm, with 44 for each.
  • Warp thread the core-sheath yarn is inserted; this gives a distance between two adjacent core-sheath yarns in the warp direction of 16 mm;
  • Weft density: 155 wefts / dm, with the core-sheath yarn inserted for every 24th weft; this gives a distance between two adjacent core-sheath yarns in the weft direction of 16 mm;

Diese flächige Textilie weist bedingt durch die Abstände der Kern-Mantel-Garne mit leitfähigen Carbon-Monofilamenten in Kett- und Schussrichtung von jeweils 16 mm als Messwert einen Abschirmfaktor nach EN 1149-3 von S = 0, 36 auf. Der zusätzlich nach EN 1149-1. 2006 gemessene Oberflächenwiderstand als weiterer Wert für die Bewertung der antistatischen Wirksamkeit liegt bei 1 x 1012 Ohm.Due to the spacings of the core-sheath yarns with conductive carbon monofilaments in warp and weft direction of 16 mm each, this flat textile has a shielding factor according to EN 1149-3 of S = 0.36 as the measured value. The addition to EN 1149-1. Surface resistance measured in 2006 as a further value for the evaluation of the antistatic efficacy is 1 x 10 12 ohms.

Das Gewebe wird mit einer Klebstoff-Pastenpunktbeschichtung von 52 Punkten/cm2 und Beschichtungsauflage von 18g/m2 beschichtet, wobei der Klebstoff aus COPES besteht.The fabric is coated with an adhesive paste dot coating of 52 dots / cm 2 and a coating coating of 18 g / m 2 , the adhesive consisting of COPES.

Es erfolgt eine Kaschierung mit einer Polyestermembran mit einem Flächengewicht von 18 g/m2.There is a lamination with a polyester membrane with a basis weight of 18 g / m 2 .

Das so hergestellte erfindungsgemäße textile Flächengebilde weist einen Abschirmfaktor S von 0,61 auf. Der Oberflächenwiderstand liegt bei 7 x 1010 Ohm und der Halbwertzeitfaktor t50 bei 0,01 s.The fabric according to the invention thus produced has a shielding factor S of 0.61. The surface resistance is 7 x 10 10 ohms and the half-life factor t 50 is 0.01 s.

Der Vergleich der Messwerte zeigt deutlich, dass die antistatische Wirksamkeit des erfindungsgemäßen textilen Flächengebildes höher ist als bei der flächigen Textilie, was aus der Kombination mit der Doppelpunktbeschichtung und der Polyestermembran resultiert.The comparison of the measured values clearly shows that the antistatic effectiveness of the textile fabric according to the invention is higher than in the case of the flat textile, which results from the combination with the double-point coating and the polyester membrane.

Beispiel 2Example 2

Es wird als flächige Textilie ein Kettengewirke mit Schussfadeneintrag mit folgenden Parametern hergestellt:

  • Kettfaden: Filmamentgarn aus 100 % Polyamid texturiert, Feinheit 11 dtex f 7;
  • Schussfaden:Filamentgarn aus 100 % Polyamid texturiert, Feinheit 11 dtex f 7;
  • Kern-Mantel-Garn in der Kette:
    • Feinheit 39 dtex f 6 x 1 mit Filamenten mit einem Kern aus trilobalem Monofil-Carbon-Filament und einem Mantel aus Polyamid;
  • Kern-Mantel-Garn im Schuss:
    • Feinheit 39 dtex f 6 x 1 mit Filamenten mit einem Kern aus trilobalem Monofil-Carbon-Filament und einem Mantel aus Polyamid;
It is produced as a flat textile a warp knit with weft insertion with the following parameters:
  • Warp Thread: 100% Polyamide filament yarn textured, fineness 11 dtex f 7;
  • Weft: Filament yarn of 100% polyamide textured, fineness 11 dtex f 7;
  • Core coat yarn in the chain:
    • Fineness 39 dtex f 6 x 1 with filaments having a core of trilobal monofilament carbon filament and a sheath of polyamide;
  • Core coat yarn in the weft:
    • Fineness 39 dtex f 6 x 1 with filaments having a core of trilobal monofilament carbon filament and a sheath of polyamide;

Dieses Kettengewirke hat eine Feinheit von 32 Gg (32 Fäden auf 1 inch). Jeder 30. Kettfaden und jede 55. Maschenreihe ist mit dem Kern-Mantel-Garn belegt. Die Schussfadendichte ist 340 Schussfäden/dm, die Masse je Flächeneinheit des Kettengewirkes beträgt 20 g/m2.This warp knit has a fineness of 32 grams (32 threads per 1 inch). Each 30th warp and every 55th course is covered with the core-sheath yarn. The weft density is 340 wefts / dm, the mass per unit area of the warp knitted fabric is 20 g / m 2 .

Die so hergestellte flächige Textile weist bedingt durch die Abstände der Kern-Mantel-Garne in Kett- und Schussrichtung von jeweils 16 cm als Messwert einen Abschirmfaktor nach EN 1149-3 von S = 0,32 auf. Der Halbwertzeitfaktor t50 beträgt 0,01 s und der Oberflächenwiderstand 1 x 1012 Ohm.Due to the spacings of the core-sheath yarns in the warp and weft directions of 16 cm each, the flat textile produced in this way has a shielding factor according to EN 1149-3 of S = 0.32 as measured value. The half-life factor t 50 is 0.01 s and the surface resistance is 1 × 10 12 ohms.

Diese flächige Textilie wird gemäß Beispiel 1 punktuell mit Klebstoff versehen und mit einer PTFE-Membran kaschiert. Danach weist das textile Flächengebilde einen Abschirmfaktor von S = 0,59 auf. Der Oberflächenwiderstand beträgt 7 x 1010 Ohm.This sheet textile is provided in accordance with Example 1 selectively with adhesive and laminated with a PTFE membrane. Thereafter, the textile fabric has a shielding factor of S = 0.59. The surface resistance is 7 x 10 10 ohms.

Auch dieses Beispiel zeigt, dass durch die Kaschierung der Abschirmfaktor und Oberflächenwiderstand beachtlich verbessert werden, wodurch auch insbesondere die Einwirkung auf Milbenallergene beträchtlich reduziert werden kann. Offenbar wird die Ableitfähigkeit für elektrische Ladungen dadurch begünstigt, dass sowohl das Membranfolienmaterial als auch das Material des Klebstoffs aus der Luftfeuchtigkeit oder aus Körperausdünstungen Wassermoleküle und/oder OH-Gruppen aufnehmen, so dass die Leitfähigkeit des Systems erhöht wird.This example also shows that the lamination considerably improves the shielding factor and surface resistance, which in particular can considerably reduce the effect on mite allergens. Apparently, the discharge capacity for electric charges is facilitated by the fact that both the membrane sheet material and the material of the adhesive from the humidity or Körperausdünstungen absorb water molecules and / or OH groups, so that the conductivity of the system is increased.

Zudem wird durch die Membranfolie das Durchdringen von Allergenen und Hautschuppen vermieden, so dass das erfindungsgemäße textile Flächengebilde insbesondere für Schutzbezüge für Kissen, Oberbetten und Matratzen geeignet ist. Schlafstörungen werden durch die verbesserte elektrostatische Ableitung ebenso vermieden wie Beeinträchtigungen durch Milben. Dadurch dass die Membranfolie lediglich punktuell mit Klebstoffpunkten angeklebt ist, verbleiben für den gewünschten Wasserdampfdurchtritt ausreichend große freie Flächenbereiche von z. B. > 90 % der Folie.In addition, the penetration of allergens and dander is avoided by the membrane film, so that the textile fabric of the invention is particularly suitable for protective covers for pillows, duvets and mattresses. Sleep disturbances are avoided by the improved electrostatic discharge as well as mite disturbances. Due to the fact that the membrane film is glued only occasionally with adhesive dots, remain for the desired water vapor transmission sufficiently large free surface areas of z. B.> 90% of the film.

Wesentlich ist, dass das erfindungsgemäße textile Flächengebilde nicht geerdet verwendbar ist und dabei die hervorragenden beschriebenen Eigenschaften aufweist.It is essential that the textile fabric according to the invention can not be used in a grounded manner and has the outstanding properties described.

Im Rahmen der Erfindung werden insbesondere Garnstärken bzw. Garnfeinheiten der elektrisch leitenden Garne verarbeitet, die den Garnstärken bzw. Garnfeinheiten entsprechen, aus denen das kombinierte Flächengebilde hergestellt ist. Dazu werden z.B. sechs Filamenten aus elektrisch leitendem Garn umwunden mit einem Umwindungsgarn aus nicht leitendem Material, z.B. aus Polyester.In the context of the invention, in particular yarn counts or yarn counts of the electrically conductive yarns are processed which correspond to the yarn counts or yarn counts from which the combined fabric is made. These are eg six filaments of electrically conductive yarn wound with a Umwindungsgarn of non-conductive material, such as polyester.

Grundsätzlich sind die Einzelfilamente der elektrisch leitenden Garne wegen ihrer Feinheit auf üblicherweise verwendeten Web- und Wirkmaschinen nicht ohne weiteres verarbeitbar. Aus diesem Grund werden je nach Anwendungsfall mehrere Filamente zusammengefaßt und mit mindestens einem die Festigkeit der Filamentschar erhöhenden Umwindungsgarn aus nicht leitendem Material, z.B. Polyester, umwunden.In principle, the individual filaments of the electrically conductive yarns are not readily processable because of their fineness on commonly used weaving and knitting machines. For this reason, depending on the application, a plurality of filaments are combined and with at least one of the strength of the filament bundle increasing Umwindungsgarn of non-conductive material, e.g. Polyester, wound.
